@TonyG sorry that you are finding yourself in a bad place at the moment.
There is so much here to relate to, all of the way from the first line of your lead post.
Irritability, and difficulty concentrating are both characteristics for many of us, as we are now. what sets us off is highly individual.
This is an exaggerated caricature, to illustrate what I'm going to try to say:
Supporter's first post:
"I met this guy on a dating site three hours ago. He told me he was a vet. and has PTSD. We seemed to be getting along so well and now he's gone silent on me.
I'm so worried and upset.
What can I do?"
I don't think I've seen anyone
that sensitive, but there are people who are almost
that sensitive and as the guys have said we don't get the back story of why, but occasional trolls aside, they clearly
are sensitive.
Some people seem to have the psychological equivalent of third degree burns. no skin at all, no protection or tolerance for certain stressors.
I couldn't believe that anyone could get bullied by and fall out with as many people as one of my exes. At least I couldn't believe it when I was still with her, I can believe it now! That's how she was. For her, a week at work without feeling bullied or seriously invalidated would have been a major post worthy event (I don't think she's a member here).
For living my life more normally and more fulfilling, I've learned so much in the year I've been coming here, from the mundane day to day posts of our amazing members, 14 years old and upwards.
